HUMIDIFIER FQB HOT-AIR FURNACES.

Be it known that Y we,

ARMBRUSTER, J r., of Rochester,

, declare the followi exact description FREDERICK W.

and GERARD C. BETLEM,

in the county of Monroe and York, have invented certain new and useful Improvements in Humidig fiers for Hot-Air Furnaces; and

ng to be a full, clear, and

we do of the same, taken in accompanying drawof tlllS specification.

The object of our invention is to provide a humidifier of. this in construction,

more eficient in use kind which is simple economical to make, and

than humidifiers here- More 4 specifically the kind object of our invention is to provide a comprising -a housing adapted to project into the heating chamber of the furnace and provided with means for atomizing a continuous stream of water or other liquid which is quickly vaporized when the hot air in it comes into the heating chamber.

contact with A further object of our invention is to provide ad ustable bafie plate roved atomlzing means comprising an whereby the amount of atomization can be controlled to meet the requirements To these and f atmospheric conditions. other ends our lnvention resides in certain combinations and arrangement of parts described and as hereinafter more particularly pointed out 111 fully the claims at the endof this specification.

In the drawings:

Figure 1 is a sid e elevation of a hot air furnace a portion of the heating chamber bein sectioned away to show one form of our invention applied thereto.

is shown our im- ,the wall 2 and serves 14:, enters be held in an through which it may escape and 7. The rear, or inner end of the housing, is closed by the wall 9, which extends inwardly and upwardly from. the bottom wall 5. The front, or outer end of the housing, is closed by the vertical wall 10, which is provided with a central opening 11. The housing 4 is provided with an outwardly projecting flange 12, which engages to seal the opening in the chamber and to provide means for securing the humidifier in place in the heating chamber.

A bracket 13, secured in any suitable manner as to the housing 4, supports a valve having a nozzle 14 in front of the opening 11 in the wall 10. Connected with the nozzle 14 is a conductor 15 leading to any suitable source of water supply under pressure. Means, controlled-by the valve stem 16, are provided for regulating the discharge from the nozzle 14.

The jet of water, delivered by the nozzle the housing through the opening 11 in its front wall and strikes against the baflle 17 arranged in its path and supported in any suitable manner. As shown, the battle 17 is mounted on a bracket 18 secured to the inner wall 9. We have provided.

means for permitting adjustment of plane or face of the baflle relatively to the axis of the jet in order to control or vary the amount of atomization taking place. For this purpose, the baflie 17 is pivotall mounted to swing on its bracket and is a apted to position of adjustment by means of a race 19 adjustable on the material, and provided bracket 18.

inlet near its base. and hot-air. outlet at its to opening in the wall in any suitable or Only a fractional part of the water of the jet is atomized, the remainder flows ofi the bafiie and falls to the bottom of the housing.

5, ,which is provided with an opening housing 4 from the hous-f ing to thepipe 20 through which it may be le vto a drain or other suitable place.

In operation, the jet from the nozzle 14 is forced against the bafiile 17, where a portion of it is atomized and rises through thetop of the housing where it comes in contact with the rising heated air in the heating chamber and is such it is carried with the air to the living rooms or other apartments to be heated. Theamount of atomization can be readily varied or controlled to meet any ordinary requirements- Itwill also be noted that our invention provides means for breaking up the water into very small particles, in which form it can readily absorb the heat required for vaporization, and that the small particles or mist is delivered to the'heated part of the furnace by means of the air current, induced by the difierence in pressure between the air in the heating chamber and the air'outside the chamber, through the housing 4, when the furnace is in operation;

While we have shown our invention applied to a hot-air furnace, it will be understood that it canreadily be used with any form of heater such as, gas-fired furnaces, electric'heatel's, steam or hot water radiators, etc., without departing from the spirit or scope of our invention.

Having described our invention what we claim and desire to secure by Letters Patent 1s:

1. A humidifier for hot-air furnaces comprising a housing adapted to project into the heating chamber of the furnace and having an opening communicating with the chamber, means for projecting a jet of water into the housing, a bafile in said housing for converted into vaporl As atomizing the jet and adjustabe to vary the amount of atomization, and means for securing the baffle in adjusted position.

2. A humidifier for hot-air furnacescomprising a housing adapted to project into the heating chamber of the furnace and having an opening communicating with said chamber, a nozzle adapted to project a jet of water through an opening in the front wall of the housing, a baflie in said housing for atomizing the jet and directing the atomized. water to theheating chamber through the opening in said housing, and means'for controlling the amount of atomization.

. A humidifier for hot-air furnaces comprising a housing adapted to project into the heating chamber of the furnace and having an opening communicating with said chamber, a nozzle adapted to project a jet of water through an opening 1n the front wall of the housing, a bafle in said housing for atomizing the spray and adjustable to vary the degree of atomization said battle being also adapted to direct the atomized jet to the heating, chamber, and means for draining said housing.

4. A humidifier for hot air furnaces co1nprising a housing adapted to project into the heating chamber ofthe furnace and hav ing an opening communicating with said chamber, a nozzle adapted to project a jet of water through an opening in a wall of the housing, a bafiie in said housing for atomizing the spray and so positioned relatively to the jet of water as to direct the atomized spray to the heating chamber, and means for draining the housing.
